.SH DESCRIPTION
.sp
.LP
The \fBscf_handle_decode_fmri()\fR function decodes an FMRI string into a set
of repository entries. Any number of the entity handles can be \fINULL\fR. The
validation and decoding of the FMRI are determined by the \fIflags\fR argument
and by those arguments that are \fINULL\fR.
.sp
.LP
If \fIflags\fR == 0, any FMRI is accepted as long as it is well-formed and
exists in the repository.
.sp
.LP
If \fBSCF_DECODE_FMRI_EXACT\fR is set in \fIflags\fR, the last part of the FMRI
must match the last non-null entity handle. For example, if property is
\fINULL\fR and \fIpg\fR is non-null, the FMRI must be a property group FMRI.
.sp
.LP
If \fBSCF_DECODE_FMRI_TRUNCATE\fR is set in \fIflags\fR, there is no check for
the existence of any objects specified in the FMRI that follow the last
non-null entity handle. For example, if property is \fINULL\fR, \fIpg\fR is
non-null, and a property FMRI is passed in, \fBscf_handle_decode_fmri()\fR
succeeds as long as the property group exists, even if the referenced property
does not exist.
.sp
.LP
If \fBSCF_DECODE_FMRI_REQUIRE_INSTANCE\fR (or
\fBSCF_FMRI_REQUIRE_NO_INSTANCE\fR) is set in \fIflags\fR, then the FMRI must
(or must not) specify an instance.
.sp
.LP
If an error occurs, all of the entity handles that were passed to the function
are reset.
.sp
.LP
The \fBscf_scope_to_fmri()\fR, \fBscf_service_to_fmri()\fR,
\fBscf_instance_to_fmri()\fR, \fBscf_pg_to_fmri()\fR, and
\fBscf_property_to_fmri()\fR functions convert an entity handle to an FMRI.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBscf_handle_decode_fmri()\fR returns 0.
Otherwise, it returns -1.
.sp
.LP
Upon successful completion, \fBscf_scope_to_fmri()\fR,
\fBscf_service_to_fmri()\fR, \fBscf_instance_to_fmri()\fR,
\fBscf_pg_to_fmri()\fR, and \fBscf_property_to_fmri()\fR return the length of
the FMRI. The buffer will be null-terminated if \fIsz\fR > 0, similar to
strlcpy(3C). Otherwise, they return -1 and the contents of buffer are
undefined.
